What is redox in chemistry.
Redox Reactions are oxidation and reduction reactions that happen simultaneously in a chemical reaction and in this, the reactant undergoes a change in its oxidation state. Redox stands for Reduction – Oxidation. Redox reaction is a common term used in both Chemistry and Biology.
Oxidation Numbers. By definition, a redox reaction is one that entails changes in oxidation number (or oxidation state) for one or more of the elements involved. The oxidation number of an element in a compound is essentially an assessment of how the electronic environment of its atoms is different in comparison to atoms of the pure element.
